How To: 97 Tib. Header Install - Hyundai Performance Forums

Corgold · 06-08-2003, 02:10 AM

I decided to throw in a quick how to on this since someone asked about it in dweets post on his own install. Like Dweet, I used the OBX 4-2-1 header.

Heres mostly what I needed (may have forgot to put a few things in here): A rachet set with a bunch of different sizes (10mm, 14mm, 15mm, and 16mm I believe), some scissors that will cut metal, jack stands, and some gaskets.

I started mine by unbolting the heat shield that covered the stock header. Before you do this, you might as well unbolt the 3 bolts from the power steering motor thing because that will definately help later on.

Once the shield is off, unbolt the 9 bolts that are in the front of the header. There are also bolts under the car. Once everything is off, rip it out. Well, that was pretty easy, and its not too tough as you continue.

Next, like Dweet did, take out the fan on the pasenger side. This is held in by 4 bolts, using a 10mm socket you can easily take this out. Now put the new gasket in place and slide the header down from the top. I put the bolts on losely just so the header would stay there, but i still have some ability to move it a little. Now to under the car, where you connect the piece that the O2 sensor will plug into. So hook all that up with the gaskets as well. Now that everythign is in place, go back through and tighten everything up real good so it wont fall off

Drop the fan back into place, adn hook your power steering stuff back up and you are ready to go.

If you run into a problem, like I did, where the bolt is so rusted that you cant get it to losen, go buy a can of MAPP Gas. It comes in a yellow bottle andyou can get it at Auto Zone I believe. You will also need a torch handle so that you can heat the crap out of the bolt until it is almost cherry red, then pop that bad boy loose. Have plent of patience if you have to do that.

Well, that is a general over view. If you are planning on doing this, and you can any questions, let me know.

Oh yes, my Tib is an auto tranny if that means anything. And there was no tapping, filing, or anything like that needed to get it to fit, just plop it in

thanks for the how to, its exactly what i needed, i got a 98 and i plan on ordering my obx header tomorrow if all goes well. the headers arent ceramic coated right? just stainless steel? does anyone kno the power gains from this header? the website is claimin some really bull crap numbers. finally, will gaskets come with the header or will i need to buy them elsewhere?

They are stainless steel. You will have the big gasket that goes on the top of the header, but you will need to buy two small ones to hook up under the car. You can get those also at auto zone or advance auto, and they are pretty cheap. The gains are pretty good, but nowhere near what SSautochrome claims. I am assuming the gains would be even better if you had a cat back.

Do you have the new OBX header, the one with both O2 sensor bungs, or the old one with just one bung? IF you have the new header, did you still have to extend the O2 sensor wires, or did they both go in with no wire lengthning? Thanks.

buy more gaskets? "hi do u have gaskets for a 98 tiburon?"

"sorry if it aint a civic, we dont have the part"

Corgold · 06-08-2003, 08:35 PM

They do have some gaskets that will almost be an exact match for what you need, you just have to widen the wholes a little bit. To the other post, I have the header with the 2 02 bungs, but you only need to use one of them, and I did not have to lengthen the wires.

Voiddweller · 06-09-2003, 12:06 PM

I have the same one as Corgold and did not have to extend the wires either. I brought mine up from the underneath and did not have to remove the fan. I did have to take the pulley mount off though and heat the rusted bolt off. I can get the new header at a good price with the main gasket and a gasket to go between the downpipe(flexpipe) and exhaust...as far as between the header and downpipe they say you don't need one and if you are worried about it you can just use sealer but I put one on anyway....you can get them at Midas really cheap.

Hey thanks for the info. Once I get some of my turbo stuff sold I will be getting one of these. Then the only think on my car stock will be the internals, I'll have modded intake, TB, IM, headers, and exhaust.

That's probably about all I can ask for and be able to do it my driveway!

Thanks,
